Which translates IP addresses to domain names?

• A. Domain Name System (DNS)
• B. Cyber Command and Control Mission System (C3MS)
• C. CSCS
• D. Endpoint Security Solution (ESS)

Answer: (A)

The Domain Name System is the mechanism that handles how names and addresses are linked onscreen. DNS is best known for translating domain names into IP addresses, enabling a computer to connect to the right server by its human-friendly name. It also supports reverse lookups, where an IP address can be mapped back to a domain name using PTR records. This dual capability is why DNS is the correct answer for translating IP addresses to domain names. The other terms refer to tools and systems that don’t perform name-to-address or address-to-name resolution.
